Improperly laid concrete will show its age quickly. Even properly laid concrete can crack, or become pitted because of harsh weather, settling or impacts. Once a concrete surface becomes worn or damaged, you must perform repairs to stop the damage from spreading before the concrete must be removed and replaced. One method of concrete surface repair is to use thinset mortar to rebuild the top layer. Thinset mortar is a mixture of aggregates, cement and synthetic adhesives that make it bond to almost any clean surface.
